I installed the honeywell rth230b thermostat in the house for a furnace. I hooked all the yellow wire green wire and white wire up to each of the corresponding holes for each color
I have a red wire and two holes for rc and rh not sure which hole to put the wire and is it supposed to be jumpered between the rc and the rh. I don't that they are jumpered. Can someone tell how to tell if they are or not?

i installed the honeywell rth230b thermostat in the house i hooked all the wires up to each port but it will work in manual mode but it doesnt come on in auto mode. also can some one tell me how this is supposed to be jumpered between the rc and the rh. I dont that they are jumpered. can someone tell how to tell if they are or not?

Would you be a little more clear on what you did and what kind of equipment you have. Is this for a furnace or a heat pump, give us some wire colors and the terminals that you connected to.

Here you go. If you cannot figure it out from this diagram then you better call for a service man to wire it for you. Improper wiring can cause the new thermostat to short and you can also damage your HVAC system.
